I was bridge hunting in the middle of nowhere with my friends and decided to defend myself against a tree with my CCW. Problem with that was I fired off all my carry rounds and, to my shame, all the ammo I had in my house except for 5 rounds of 115 gr. WWB.

Better than nothing, but that's all I got in my gun. So I am going to order a stash of Winchester 147 gr. SXT. Problem is, I have no idea how to tell if my Glock 19 is rated for it.

I would assume so since you there is no known force on earth which can destroy my Glock (unlike my XD).

Thanks for the education.

By the way, that tree is as good as dead. All 16 shots were center mass and in a tight group.

I would bet the farm your Glock is ok +P+. Glocks main market target is law enforcement, and Federal sells a 9mm+P+ especially for law enforcement. It is available, and legal, for private use. I've shot the stuff in my new Taurus 24/7PRO. It actually doesn't "feel" much different from my Corbon, but I suppose it is. On second thought, it might possibly have a little more bump than my Corbon and Fiocci.

I don't believe there is any official standard for +P+. SAAMI is the agency that sets pressure standards for cartridges, and I don't think +P+ has any exact meaning other than "exceeds SAAMI standards."

Thus I doubt any manufacturer is going to make a blanket statement that it's okay to shoot +P+ because they would essentially be saying "you can shoot anything you are able to physically cram into the chamber."

The general advice given here and elsewhere is that modern quality firearms can probably handle +P+ ammo made by reputable name brand manufacturers. Shoot it through an antique or a junk gun, or use Brand Z Nuclear Hot ammo, and all bets are off.

+P/+P+ are not measurements they are marketing devices only, vary wildly from manufacturer to manufacturer and are generally taken to mean.

"Yo sucker, this stuff will make you bigger, badder and cooler than any other guy on the block"

Followed by REALLLLLY small print

Ammunition has been shot by a professional on a closed course. Not intended for real world use, side effects may include loss of hearing, loss of eyeball, loss of digits, coma or death. The above ammunition has not been evaluated or accepted by the FDA and any loss or injury is entirely the fault of the consumer.

In other words Caveat Emptor, shoot at your own discretion and be bloody careful

Haha. Fair enough.

I simply want some good penetration & damage so I can put my foe down. I just don't want my gun to explode while my foe laughs at me and bludgeons me to death with my shattered gun.

Real issue here is better "knock down" rather than higher velocity and not infrequently lower accuracy which is all that + ammunition will give you.
(Accuracy based upon user interaction/experience rather than inherent to the higher pressure....)

Shoot the calibre you are comfortable with, work on accuracy and shoot enough to build muscle memory.

Then look at the various EFMJ, JHP etc rounds out there and discount about 50% of the hype.

That is not correct, there are most certainly some calibers that have +P pressures specified by saami. .38spl is 17k psi, .38spl +P is 20k psi. Thats not marketing, thats a difference in measured pressure. +P+ would be anything over 20k psi in that round. There is no .380acp +P pressure specified by saami, so if you see someone selling .380 +P then its marketing.

To each his own, I don't call real pressure differences sales BS. I didn't want people to think that there is no such thing as +P when it is in fact a real standard with a measured max pressure in many caliber just like the regular saami spec'ed loads.

DOWN WITH THE ZOMBIE TREES!!!
Okay thats out of my system...but really bullet choice is more important than a +P rating. Expansion and wound channel are more important than getting an exit wound due to velocities that would make a SR71 jealous. Save the money on getting good quality factory ammo that consistantly performs well out of your gun. Hollows are going to be better for SD than FMJ's...buy a few boxes from the major loaders (Federal, Win, Hornady, and maybe even *wretch* Remington) See what JHP your gun likes best, then take down the zombie tree lords with a vengence!

FWIW I own a S&W 642. It was not marked for +P ammunition. It was mfg. in 1991. I called S&W. They stated that it was not approved for +p. I do not shoot +P in it. I am having problems finding non +P SD ammo. for it.
